Recycled polypropylene reinforced with curaua fibers by extrusion

Journal of Applied Polymer Science, 2009
AbstractCuraua fibers were studied as reinforcing agents for postconsumer polypropylene. The composites were processed by extrusion. The composite properties were investigated by mechanical tests, thermal methods, melt flow index, surface morphology, and water uptake.

Influence of Alkaline Hornification Treatment Cycles on the Mechanical Behavior in Curaua Fibers

Macromolecular Symposia, 2018
A well‐known treatment applied in vegetable fibers in both paper and cellulose industry is named hornification. This treatment consists in soaking and drying cycles aiming promoting a reducing in the water absorption capability of the fibers, which causes a stiffening in the cellulosic structure increasing the dimensional stability and consequently ...

Cellulose nanofibers from curaua fibers

Cellulose, 2010
Curaua nanofibers extracted under different conditions were investigated. The raw fibers were mercerized with NaOH solutions; they were then submitted to acid hydrolysis using three different types of acids (H2SO4, a mixture of H2SO4/HCl and HCl). The fibers were analyzed by cellulose, lignin and hemicellulose contents; viscometry, X-ray diffraction ...

Mechanical Behavior of Unidirectional Curaua Fiber and Glass Fiber Composites

Macromolecular Symposia, 2012
AbstractSummary: This work intends to promote the use of natural fibers by comparing the behavior of isophthalic polyester matrix composites reinforced with unidirectional curaua fibers with that of unidirectional glass fiber composites. The composites were produced varying the reinforcement angle (0°, 15°, 30°, 45°, 60°, 75° and 90°) with the aim of ...
